I'd like to see what I made for each quarter of last year, is there somewhere I can get that info?

Not for each quarter. That much detail is YOUR responsibility. You can obtain the total per employer PER YEAR from the IRS or SSA

Ask your previous employers? Do you have your check stubs?

Sure, you can request a social security statement. Or, you can look at your paystubs, or your W4 form from last year.
